A good example would be; if you had a Sorcerer with all attribute points into Magicka. He/She would have very low health. Therefore, they have to cast a shield every so often to absorb the damage so it doesn't effect their health directly. There are more than one type of damage absorbing shields and they can all be "stacked" at once. Hope this helps ya and welcome!! ^.^
